The ossification of posterior longitudinal ligament of the spine(OPLL) is newly recongnized clinical entity,although compression of the spinal cord by an OPLL was reported by key as early as in 1839 in Guy's HospitalReport. OPLL was noticeable in lateral tomography as an abnormal dense radiopacity along the posterior margins ofthe vertebral body. Authors retrospectively analysed the diagnostic values and findings of lateral tomography ofthe cervical spine in 11 cases at Kang Nam General Hospital Public Corporation during 1 yr from July 1984 to June1985. The results were as follows; 1. Among suspected 11 cases of OPLL, 9 cases were confiremd as OPLL on lateraltomogram. 2. Age range was 25 years old to 55 years old and more prevalent age was over 5th decades & male wasmore involved than female. 3. Frequent involvement was C2-C5 level and number of vertebral bodies involved was 3.6in average. 4. This ossification developed 4 modes, a continuous type 11%, segmental 33%, mixed type 33%,circumscribed type in 22%. 5. OPLL thickness were from 2mm to 4.5mm and spnal canal narrowing ratio were form 25%to 44% and there were norational relationships between clinical symptom and thicknness of OPLL. 6. On diagnosis ofOPLL, lateral tomography is accurate and recommendable screening study due to easy, noninvasive, indisipensable and less harmful technique, compared to those of myelography or computed tomography.

The CT is a more accurate technique for detecting sclerotic bony change of osteritis condensans ilii thanplain radiograph. We analysed a comparison between CT and plain radiography of osteitis condensans ilii, acorrelation between osteitis condensans ilii and women of childbearing age. The result were as follow: 1. Theincidence of osteitis condensans ilii is 5.3% on KUB, 11.7% on CT when the width of iliac sclerosis is more than7.5mm as diagnsotic criteria. 2. We observed a osteitis condensans ilii between 19 years and 51 years of age, mostfrequently in fourth decade. 3. The width of iliac sclerosis is 10-13 mm in 3 cases of osteitis condensans ilii onboth CT &KUB, 7.5-9mm in 4 cases of osteitis condensans ilii on CT only. 4. The incidence of osteitis condensansilii is increased significantly when the width of iliac sclerosis is less than 7.5mm as diagnostic criteria. 5.Relatively high correlation between osteitis condensans ilii and delivary in our study (66.6%)

Normal" spinal posture is generally accepted as moderate lordosis of the cervical and the lumbar sections ofspine and moderate kyphosis of the thoracic and sacrococcygeal sections. Among these normal range of the lumbarlordosis is less well defined. CT is very useful method to identified the bony structure and adjacent soft tissueof the spine, so it is very available method to detect accrate lumbar lordotic angle by using lateral Scanogram.Analysis and comparison of lumbar lordotic angles, crossing angle are drawn each parallel line to the superior endplate of body of 1st. lumbar vertebra and to the inferior end plate of the 5th. Lumbar vertebra, in 174 cases withbackache and 50 cases normal groups at Kangnam General Hospital Public Corporation, from Aug. 1985 to Jul 1986.Male and female were almostly same affected in backache group (1.1:1). And most lumbar lordotic angles were 10 degrees to 40degrees between all backache age group. On backache group, over all mean lumbar lordotic angleswere 24.7±8.9degrees but no significant difference at mean value of the each disease, such as HIVD, DegenerationSpondylosis or No Remarkable Finding group. On control group, over all mean ones were 29.2±8.0degrees. So,significant difference of lumbar lordotic angle between backache and control group, and most difference is at 5th.decade group(p<0.01).

The purpose of this study was to investigate the displacements of cast framework by torch soldering and electric soldering techniques. Specimen had two cylinders and connecting bar that had sectioned with 0.3mm gap at mid point. 10 of total specimens were divided into two groups. In torch soldered group, soldering investment block was made and conventional torch soldering procedure was carried out. In electric soldered group, electric soldering was carried out on the master cast without soldering investment block by using electric soldering machine(Dentapunkt DP 7, Kulzer, Germany). After soldering procedure, three dimensional coordinates of two centroids of each cylinder were measured by three dimensional coordinate measuring machine. The intercentroidal displacement and global displacement were calculated and then, these values were compared and evaluated. The results were obtained as follows: 1. Intercentroidal distances of specimens decreased after both soldering procedures, and the decrease in intercentroidal distance was greater for torch soldered group than for electric soldered group 2. Global displacements of torch soldered group were greater than those of electric soldered group

Thirty patient with essential hypertension were administered Manidipine, a new calcium antagonist, 10~20mg once daily to evaluate the hypotensive efficacy and safety for 8 weeks. And the followings were the result. 1) Patients were consists of 14 male, 16 female, aged 53 in average and classified as mild in 21 and moderate in 9 patients. 2) Optimum intial dose was 10mg and 10 to 20mg were the doses recommended. 3) Blood pressure dropped after 8 weeks 24/13mmHg in average, rewarding 80% effectiveness and normalized in 87%. 4) Most frequent side reaction was facial flushing in 5 patiens followed by palpitation and dizziness, all of which did not disturb the continuation of medication. 5) Most of routine laboratory parameter were normal and unchanged between before and after the trial. 6) Overall rating of usefulness was 77%. In conclusion, Manidipine 10 to 20mg once daily regimen is well tolerated and effective in the treatment of mild to moderate essential hypertension.

Chronic bronchiolitis is a condition associated with cigarette smoking, and later associated with pulmonary parenchymal alteration and progressive deterioration of lung function. Early respiratory bronchiolitis was produced in Sprague-Dawley rats by indirect inhalation of cigarette smoke daily in a smoke exposure chamber designed by authors for 1 month. Experimental group A (n=5) was sacrificed after having smoked 30 cigarettes, group B (n=5) after 80 cigarette, and group C (n=7) after 140 cigarettes, respectively. Examination of morphologic changes in the lungs was done on light microscope, transmission and scanning electron microscopes. Light microscopically, increase in number of goblet cells in the bronchial mucosa, brown-pigmented macrophages in the alveoli, multifocal alveolar collapse adjacent to the bronchioles, dilatation of alveolar ducts and alveolar spaces were observed. Transmission electron microscopically, irregularly shaped Clara cells, alveolar wall collapse, and focally type I epithelial cell injury were seen. Scanning electron microscopically, scattered alveolar collapse, irregular dilatation of alveolar ducts, alveolar spaces and interalveolar pores (pores of Kohn) were seen. The terminal and respiratory bronchioles showed morphological alteration of Clara cells, but no evidence of cellular bronchiolitis or bronchiolar obstruction. We conclude that sidestream smoke induces an early respiratory bronchiolitis including aggregates of brown pigmented macrophages and varying degrees of structural alteration of adjacent pulmonary parenchyma.
